WRAPPER FOR EXPANSIBLE IIIATERIAL Application fiieanme-e, 1928; Serial No. 284;043.

This. invention relates. to an improved method of. packaging expansible material and the wrapper therefor, andfrelates moreparticularly to the packaging of such material. as cotton, wool ,.cotton. or woolwaste,

material, and thenplace metal bale ties about the package or bale at intervals to hold; the

material. in its compressed state and retain the fabric. strips thereon.

Thismethod of packaging is open: to va-.

rious objections since the burlap orv fabric employed. adheres strongly to the. material. and is capable of. complete removal only. at the cost of considerable labor. and expense-z.

Moreover, dirt, dust, ink metal bale tie rust and other foreign matter passes readily through the coarse weave of the fabric and;

Works its way into the packaged. material,

and in the usual method of=forming the pack-- age a considerable portion of the package is not covered by the fabric. The presence of such foreign matter in thematerial entails a considerableloss of material aswell as great expense for cleaning the damaged material.

Attempts tomake use of paper as a cover for such expansible material have not met with success heretofore as the expansiveness of. the material has caused the'paper to tear:

between thebale ties, Whether or not fabric coversv were, placed. over the paper; whereby; the packaged-material, or portions thereof,

was leftgwithout. adequate: protection.

It is the object ofthepresentginvention to.

overcome these diffiCHltlGS and? provide a: more expeditiousimethod of: packaging such materials by providing a covering made up.

ofrpleated' or gathered paper strips capable of. unfolding sufficiently to allow for the eXpansiveness inherent in the material, whereby tea-ring of thecover will her-substantially obviated, aswell as to provide a;suit-;- able. wrapper and method of applying the: same for; substantially or. entirely enclosing theimaterial and thus preventing injury-to. .the material. through contact with fbreign:

matter.

Another object of. the invention istoi pros VlClG a pleated: or gathered. paper coverfor expansible materials which iscapable of use.

either with. or without any'additionaltfabric cover extending throughout the. whole. or partv of; the.-v sup'erficial. area of. the package and to formthe paper. cover; in two or" more;

In the embodiment of the invention illustrated in Figs. 1 to 3 of the dr wings, I designates a quantity of expansible material to be packaged which is shown in the various figures in the form which it may assume after compression, the same being roughly that of .a rectangular solid known as a parallelepiped.

The method of packaging and wrapper described herein are applicable for use with any inherently expansible material which is ordinarily subjected to some compression before the ties or other retaining means are applied thereto, whether such compression is aifected in a press or by drawing the retaining means closely therearound to compact and bind the material, although it is particularly applicable in connection with the packaging of cotton, wool, hair, cloth and the like.

The topmost paper sect-ion or wrap as shown in Fig. 1 is designated by the numeral 2 and may be and preferably is in the form of a composite sheet made up of two or more sheets each of which is provided with a plurality of pleats or folds 3. hen the paper section or wrap is made up of two or more separate paper sheets one or more of said sheets may be unpleated if desired, although for general purposes I regard it as preferable that each of the sheets be provided with pleats; and the several sheets, or as many of them as it is desired to provide with pleats, may be pleated together so that the pleats of the several pleated sheets interr'it, or the pleats may be formed separately in the several sheets and the sheets then brought together to form the cover section or wrap with the pleats in each sheet corresponding with or offset relative to the pleats of the other sheets. I prefer, however, that the pleats of each sheet be offset somewhat relative to the pleats in the other sheets which are superposed upon each other to form the cover section or wrap in order to secure greater uniformity in the thickness of the cover section. The several sheets forming the cover section may or may not be joined together at intervals throughout their extent as by stitching, stapling, folding, creasing, or otherwise in order to effect a temporary or more or less permanent connection between the several sheets in order that the section may be handled as a unit in applying it to the material. It is to be understood that the above description of the manner of forming the cover section or wrap 2 applies also to each of the other paper sections employed in covering the material.

The topmost paper section or wrap 2, as shown, is formed with free end portions l and 5 each of which is adapted to extend a considerable distance beyond the ends 6 and 7 of the material for a purpose which will be more fully set forth hereinafter. The lower paper section or wrap 8 as shown in Fig. 1 may be made as shown in that figure of only substantially sufficient length to extend to or slightly overlap the ends 6 and 7 of the material as indicated at 9. The cover section 8 may be formed in all respects as the cover section 2 previously described, and comp 'ises preferably a plurality of separate paper sheets, some or all of which are provided with pleats 10 arranged parallel to each other and to the bale ties 11 as finally applied to the package.

In order to make the illustration more clear the ends 4; and 5 of the paper section 2 are shown as projecting directly outwardly from the ends 6 and 7 of the material, and the sections 2 and 8 are indicated, for the purpose of clearness, as being each formed of a single sheet of pleated paper although they may be and preferably are made up of two or more sheets.

Where the material packaged is such as is compressed in a power press of any type, it is shown in Fig. l in the form it assumes after having been compressed, the sections 2 and 8 having been applied before compression or after the material has been partially com pressed, and the bale ties 11 are then applied, as is customary, before removing the bale from the press. The ends 12 and 13 of the section 8 are folded over the ends 6 and 7 of the material as at 9, either in placing the sheet 8 in the press or after the removal of the bale therefrom.

After removing the package or bale from the press, the ends 4 and 5 of the section 2 are then folded over the respective ends 6 and 7 of the material, as shown in Fig. 2, to entirely cover the ends 6 and 7 of the material and preferably form overlapping edges 14 extending slightly beyond the ends 6 and 7.

After the ends 4- and 5 of the section 2 have been folded over the ends 6 and 7 of the material I preferably apply a fabric end cover 15, which may be formed of a coarse burlap, cotton, or other fabric, to each end of the bale or package so that the edges 16 thereof extend over the sides of the bale a suliicientdistanceto: be engaged--by a hale tie. A bale tie 17 may then he applied over the edge 16 of the fabric and drawn up to hold the fabric in place and bind the end of the bale. After the application of the bale tie 17 the" previously applied bale tie 11, located atth-eend of the bale, may be removed if desired and the tie 17 thus serve the double purposeof holding the fabric and acting. as the end tie of the bale.

In the modifiedform of the invention as shown in Figs. t and 6 the material 1 is shown after it has been compressed as in the form previously illustrated, and the uppermost paper section 2: is provided with pleats or folds 3 extending throughout the entire length thereof. The paper section or wrap 2 has the free ends 4 and 5 extending beyond the ends 6 and 7 of the material a sufficient distance to serve as covers for the ends 6 and 7 of the material respectively, when folded thereover.

The cover sections or wraps 2 and 8 may be formed from separate sheets, as previously described in connection with the form of the invention as shown in Figs. 1 and 8, and are provided with pleats 3 and 10 respectively, as in the previously described embodiment of the invention. The invention shown in Figs. l and 6 differs from that previously described in that paper side sections 20 are provided for attachment to each side of the bale to serve as a cover for that portion of material ordinarily exposed between the side edges of the cover sections 2 and 8 or as covers for the cuts formed in sampling the bale. Each side section 20 may be of composite construction, that is, formed of two or more separate sheets all or a part of which sheets are provided with pleats 21. The number and arrangement of the several sheets and the pleats or folds therein may be the same as employed in the formation of the cover sections 2 and 8 previously described, or, if desired, the side sections may be formed from a single sheet of pleated paper or from a lesser number of sheets than is required in the formation of the cover sections 2 and 8. It is preferred that the side sections 20 be provided with pleats 21 which extend substantially parallel with those pleats in the cover sections which overlie the sides of the bale. Each side section is provided with a line of adhesive 22 upon the side edges thereof for securing the edges to the outer face of the cover sections 2 3 and 8.

In forming the package shown in Figs. .4 and 6, the coversections 2 and 8 are applied as previously described. and, after the material has been compressed, but before the ties 1]. are applied, the side sections 20 are placed upon the sides of the bales and may be secured to the cover sections 2 and 8 after the removal of the bale from the press by the adhesive 22. The bale ties 11 are then applied and the bale removed from the press. The

ly secure the end covers 15 against the removal and,;if desired, the end ties 17 may take the place of the end ties 11 previously applied, as

the case of the previously described embodiment of the invention. Qne forill Of, composite sheet such as ma be used as a cover section or as a side section for the purpose" specified is shown in Fig. 5, wherein 24, 25 and 26 designate three paper v sheets provided with pleats 27, 2.8 and 29 respectively. As shown these pleats are formed separately in each sheet, and the sh ets Superposed upon each other with the pleats of the separate sheets slightly offset from each other to formthe composite cover section. V

As in the case in Figs. 1 and 3, the form of the invention shown in Figs. fl and 6 is illustrated as though the cover sections 2 and 8 and side sections 20 were each composed only of single pleated sheets, but this show ing is for the purpose of clearness and in order that the disclosure may not be confused by a multiplicity V of lines indicating separate sheets, it being understood that the cover sections in both cases, and the side sections when desired are to be formed from two or more Sheets, which may be formed and arranged after the'manner set forth in detail in connection with the cover section 2 as described above. I regard it as preferable that the cover sections 2 and 8 be formed substantial- 1y afterthe manner illustrated in Fig. 5, although- I do not limit the preferred form to theexact number of sheets shown in Fig. 5, as a greater or less number may be used. The form of composite sheet shown in Fig. 5 is also regarded as preferable for forming the side se tions although a lesser number of sheets maybe used than is shown in that figure.

While I have shown the package as formed by the uppermost paper section 2 being ex tended a sufficient distance at each end of the material to: provide a cover for both ends of the material, it is to be understood that my invention is not to be limited to this particularmethod of providing end coverings for the package and that I may form the top and bottom cover sections of substantially equal lengths and extends each of them at 013 posite ends of the bale a suflicient distance so that the free end of one cover section may be employed to cover one end of the bale and the free end of the other cover section used to cover he oth end at t e bale, er I may arrange two cover sections so as to provide free end portions of each section extending beyond both ends of the bale and fold the free end of both cover sections over both ends of the bale whereby a free end of both sections will overlie a portion of each bale end and the two adjacent free ends provide a complete cover for each bale end.

Although I have shown the burlap or woven fabric cover sections as applied only to the end portions of the bales I may use either a single sheet of pleated paper or a plurality of such sheets for forming the cover sections 2 and 8 and the side sections 20, and then apply a burlap or woven fabric cover so that it will overlie the paper sections and extend entirely or substantially over the entire surface of the bale, in order to provide a more complete and substantial cover for the bale for use with such material and under such circumstances as require a more complete and fully supported Wrapping than is afforded by the pleated paper sections alone.

lVhile I have referred to the possibility of removing the initially applied end ties and substituting therefore other end ties overlying the edges of the fabric end sections, it is to be understood that this substitution of end ties is not essential to the carrying out of my improved method nor to the production of my improved package, but that the fabric cover, whether composed of end sections or of one or more sections of such size as to extend entirely or substantially through the superficial area of the bale, may be secured by bale ties applied directly after the compression of the material and before its removal from the press.

While the cover sections 2 and 8 have been shown as composed of two or more pleated sheets, and the side sections 20 are described as formed of tWo or more pleated sheets, it is to be understood that both the cover sections and the side sections may be formed from a single pleated sheet of fairly heavy paper when desired, the number of paper sheets employed in forming each section and the weight or thickness of the paper used being dependent upon the size of the package the material to be wrapped and the conditions of use as will be understood by those skilled in the art.

It will be seen from the above description that my improved method and wrapper provide a simple and eflicient method and means for protecting the usual classes of compressed expansible material from injury both in handling and in being conveyed from place to place, and possess the added advantages of being less expensive than the methods and means now commonly employed.

hat I claim is In a bale of expansible material, separate paper wraps located upon opposite sides of said bale and having end portions folded In testimony whereof I have affixed my sig nature.
